Ala. Admin. Code r. 335-3-2-.03 - Special Episode Criteria

(1) The Director shall have the authority to declare episodic conditions when the atmospheric concentration of a single contaminant or that of a specific locality within the State show elevated concentrations.

(2) Specific Pollutant Situation. When concentrations of one or two contaminants reach or exceed the defined criteria levels, and concentration of other contaminants remain substantially below 50 percent of Alert levels, and meteorological conditions are such that these specific contaminant concentrations can be expected to remain at the above levels for 12 hours or more or increase unless control action is taken, a Specific Alert, Warning, or Emergency Status shall be declared by the Director, naming the contaminants that meet the respective criteria. In such instances when two such contaminants meet different criteria, the Director shall declare the status for the episode having the higher level and that an Episode Watch is being maintained on the remaining contaminant.

(3) Specific Locality Situation. When high concentrations of one or more contaminants are measured at one monitoring site and not others and the effect is Judged to originate from an identifiable source near the given site, the Director shall declare the appropriate local Alert, Warning, or Emergency Status for the delineated area and that an Episode Watch is in effect for any remaining portion of the jurisdictional area while meteorological conditions favor the maintenance or increase of said high concentration for at least twelve (12) hours or more unless control action is taken.
